„System thinking with Aquaponic“ is an educational concept that aims to train students in system thinking by using a connected fish and plant culture system. System thinking is seen as a central skill in education for sustainability. Between October 2007 and January 2008, a teaching sequence took place with three classes of 7th grade students in the Zuerich agglomeration, Switzerland. Several themes were introduced in the lessons by means of a classroom model: what is a system, relationship between system components, feedback loops and self-regulation and finally planning and construction of an Aquaponic classroom system. The students then also operated and monitored the system. The effect of the teaching sequence on system thinking competences was assessed at the beginning and at the end of the sequence. The ability of students to think in a systemic way instead of linear succession improved significantly in the posttest compared to the pretest. In addition, gender specific differences in relation to learning systemic thinking were compared. Female students showed slightly better results than male students; the reasons for this could not be pinpointed.
